REPORT OF THE STATE ENTOMOLOGIST IQI17 9 
in the western part of the State than was the case two years ago, due, 
probably, to the work of natural enemies. 
Red bugs. Injuries by these two pests are becoming increasingly 
apparent here and there in the State and fruit growers are suffering 
considerable losses from the work of these bugs. The fact that 
there are two species, both of which may occur in the orchard, 
one being abundant a little earlier than the other, complicates control 
measures, since recommendations of value in the case of the earlier 
species are of comparatively little service if the infestation is largely 
due to the later and. lacking expert examination it is usually 
impossible to determine the troublesome form until the damage 
has been caused. 
San José scale. This pest is relatively much less abundant than 
in earlier years, this being particularly true in the Hudson valley. 
Observations and reports from all sections of the State indicate a - 
generally satisfactory control where there is thorough spraying with 
the lime sulphur wash at winter strength and in some localities 
there is little or no damage even in unsprayed orchards. The 
work of parasites, first brought to attention a few years ago, con- 
tinues and it is probable that these minute insects are not unimportant 
factors in bringing about this gratifying condition. 
Pear thrips. The situation with respect to this insect remains 
nearly unchanged. It is sporadically abundant and destructive 
here and there in pear-growing sections, especially in the Hudson 
valley, and despite efforts of fruit growers there is likely to be con- 
siderable loss before the seriousness of the infestation is appreciated. 
Pear psylla. There has been considerable pear psylla in Hudson 
valley orchards due, in some cases at least, to the delayed dormant 
spray not being held until practically all the eggs have been deposited. 
This pest, like the pear thrips, can be controlled to best advantage 
only by applications given within rather closely defined time limits 
and many growers experience difficulties in recognizing the periods 
when work of this kind can be done to the best advantage. 
Gipsy moth. Anexamination of the region formerly infested shows 
a very gratifying condition in that no living insects in any stage 
have been found within two years and the thorough spraying and 
other work prosecuted in this attempt to exterminate the insect 
augurs well for the successful completion of a difficult and costly, 
though economical, undertaking. 
Grass and grain pests. The cold weather and copious rains of 
last spring were unfavorable to the development of sufficient grass- 
hoppers to cause serious damage and in most sections these insects
